Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579134, here are decompositions:

5 + 31579129 = 31579134
7 + 31579127 = 31579134
31 + 31579103 = 31579134
43 + 31579091 = 31579134
47 + 31579087 = 31579134
61 + 31579073 = 31579134
131 + 31579003 = 31579134
211 + 31578923 = 31579134

Showing the first eight; more decompositions exist.
